The video about Athens

Hello, all

I recorded a small introductory video about Athens.
Here it is:

http://vimeo.com/40653315

(about 21 minutes).

I explain some basic stuff like drawing things using Athens canvas,
building paths, use of transformation matrices etc.

Please note, this is a first video i ever recorded in such context in
my life, so don't be too harsh :)
Also, note that the animations are jagged because of video recording
frame rate, not because it is that slow in reality.

There are still a blog post pending about it.. which i plan to finish
when i will finish ;)

Best regards,
Igor Stasenko.

Re: The video about Athens

Oh yes... and if you notice sometimes i say "we" not "me" during video.
Because i was not alone doing all the work.
I'd like to thank a LOT to Fernando Olivero for his help and
dedication with making Cairo backend for Athens!!!
He were visiting our team during March for one month and we did a lot
of things together, pushing Athens to
much useful state.

It's so great stuff!!! :))

Is cairo used as athens backend for this demo?
Is it should work with Bitblt backend?

In demo I see many usage of angel parameter for transformations. Do you think about "angel unit objects" like "90 degrees" or "2 radians" instead of raw numbers ?

How #scaledBy: works with Point argument (self extend) and Float like (frame / 100 sin abs) at the same time? What' logic?

I loaded the config and it went fine.

Got the NBCogVM from Jenkins.

But then, got issues with the 1.4 image.

FSFileSystem isn't in. What to do?

And then, after commenting out the offending part, I end up with Error: function unavailable in NBFFICallout - This by running:

| m |

m:= AthensDemoMorph new openInWorld.

m nextFigure.

m delete.

This is on Windows XP SP3. Do I need something extra? Is it not supported on Windows?

Re: The video about Athens

In reply to this post by Igor Stasenko

Looks great. I just tried to give it a try, but I get stuck.

I did the following on Mac Lion:

- I took Pharo 1.4:
http://gforge.inria.fr/frs/download.php/30620/Pharo-1.4-14438.zip
- I ran it with CogNB:
https://ci.lille.inria.fr/pharo/view/NativeBoost/job/NB-Cog-Mac-Cocoa/lastSuccessfulBuild/artifact/NBCog.zip
- I then executed:
Gofer new
squeaksource: 'Athens';
package: 'ConfigurationOfAthens';
load.
((Smalltalk at: #ConfigurationOfAthens) project version: '1.0') load.
- Then:
AthensDemoMorph new openInWorld

But I get "Error: function unavailable" for:
- #(#AthensCairoSurface #cairo_image_surface_create #(#int #aFormat #, #int #aWidth #, #int #aHeight))
- '/opt/local/lib/libcairo.2.dylib'

See the attached log.

I guess I am missing the cairo library. What should I do to get it?

Cheers,
Doru

Did you load the version Igor did in the screencast? I did and got no FS error. It's:
(ConfigurationOfAthens project version: '1.0') load.

Hi Tudor,

I'm forwarding the notes and email i've sent when i successfully compiled Cairo.
(You can check previous mails on this matter also)

Hope it helps!

---------------------------------------------------------------------------------------------------------------------------------

Regarding the build, after a lonnnngg series of errors, i also managed
to build universal binaries of Cairo, using MacPorts (brew just
doesn't ease the task of creating 32 bit libraries).
sudo port cairo +universal, worked for me, taking at least 30 min to build.

ATTENTION: Before entering the port cairo install command, I've had to
manually install appleGcc4.2, found @ [1] (file name
gcc-42-5666.3-darwin11.pkg. Given that i have Lion, XCode4.2, and if
you just allow macports to build appleGcc4.2, it will run a process
that consumes resources and finally stalls your computer!

I've attached a screen shot that may help somebody else, for setting
up the examples. Using NativeBoost Cog VM for Mac, downloadable from
NativeBoost site or Jenkins.
.....

Fernando
[1] http://r.research.att.com/tools/

sudo port install cairo +universal

file /opt/local/lib/libcairo.2.dylib
/opt/local/lib/libcairo.2.dylib: Mach-O universal binary with 2 architectures
/opt/local/lib/libcairo.2.dylib (for architecture i386): Mach-O
dynamically linked shared library i386
/opt/local/lib/libcairo.2.dylib (for architecture x86_64): Mach-O
